CONDENSATION-SASH FOR SHOW-WINDOWS.

Specification of Letters Patent.

Patented Apr. 9,1918.

Application filed July 26, 1917. Serial No. 182,915.

To all whom it may concern:

Be it known that I, \VILLIAM P. FRANCIS, a citizen of the United States, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a new and Improved Condensation Sash for Show- Windows, of which the following is a full, clear, and exact description.

This invention relates to store fronts or show windows and deals more particularly with improvements in the construction of the sash or frame.

The invention has for its generalobjects to improve and simplify the construction of devices of this character so as to be reliable and efficientin use, comparatively inexpensive to manufacture, and so designed as to afford an efiective drain for the condensation on the glass.

A more specific object of th invention is the provision of a novel form of bottom bar for the window frame or sash which embodies a gutter for the collection of condensation and also embodies means for effectively supporting a plate glass.

Another specific object of the invention is the provision of a sash or window frame in which the outer and inner sections are secured together by a novel cleat arrangement or tie members,

\Vith such objects in view and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figure 1 is a vertical section of the bottom portion of a sash or frame of a show window or store front;

Fig. 2 is a fragmentary plan view of the bottom rail or bar before the plate glass is applied; I

Fig. 3 is a vertical section on the line 33, Fig. 1;

Fig. 4c is a transverse section of the gutter containing and glass supporting bar or rail fastened to the floor of the window or store front;

Fig. 5 is a plan View of one of the cleats or tie elements; and

Fig. 6 is a horizontal section of a corner The condensation sash or frame B is composed of a bar or strip formed of parallel strip-like members land 2 of right angular cross-section, as clearly shown in Fig. 1 and having their upper parallel flanges integrally connected by a longitudinal reentrant gutter 3, which latter has at spaced intervals openings 4: in its bottom whereby water of condensation on the plate glass can drain into the chamber 5' formed between the two :iembers 1 and The member 2 has one of its flanges forming a horizontal shelf 6, under which are placed at spaced points supporting blocks 7 and on top of this shelf are arranged at spaced points felt, leather or other cushions or pads 8 on which, the bottom edge of the plate glass A rests, as'

clearly shown in Fig. 1. The vertical flange of the outer or base member 1 is fastened to the floor by a plurality of screws 9 which are accessible through openings 10 in the vertical gutter-supporting flange of the member 2, as shown in Fig. 4:. U

The plate glass is clamped in place by a face mold 10 which has a vertical flange 11 bearing against the outerface ofthe plate glass and clamping the inner face against the vertical flange of the member 2. The mold strip 10 has its bottom edge interlocked with the base member 1, the horizontal portion 12 of which has an upstanding flange 13 bent inwardly into a hook-shaped ledge 14;, as shown in Fig. 1, and the bottom edge of the mold 10 is bent backwardly or inwardly into a flange 15 which interlocks with the portion 14 of the flange 13. Cleats or tie elements 16 in the form of metal strips soldered to the inner surface of the mold 10 pass under the glass plate A and over the shelf 6, and the inner ends of these cleats or tie elements are split into bifurcations 17, as shown in Fig. 5. These bifurcations pass through slots 18 in the member 2 and are bent upwardly and downwardly, as shown in Figs. 1 and 3. To permit these bifurcations or lugs to be bent, a hook or other instrument is inserted through the drain openings 8 in the gutter, whereby the workmencan easily, bend the bifurcations as shown. In thi's'm'anner'no fastenings for securing the plate glass in position are required.

In the corner construction shown in Fig. 6 the glass plates A are held between an outer angle strip 20 and a pair of inner strips 21 of V-shaped cross-section, and a tie-element 22 are soldered or otherwise fastenedtothe outer strip 20 and pass between the-strips 21, sothat the bifurcations or lugs 23, corresponding to the bifurcations 17,-Fig. 5, are respectively bent oppositely so as to interlock with the strips 21. This forms a simple and effective means for binding the edges of the plate glass together without screws, bolts or other fastenings.

To permit the condensation to run out of the chamber 5 the front wall 13 thereof has openings 18 Figs. 1 and 4:. The tie elements 16 have stiffening corrugations 16.

From the foregoing descriptiontaken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: I

1. In a show window, the combination of a bar formed with an upstanding flange formed along its edge into a hook and also formed with a shelf, a plate of glass resting on the shelf, a face mold engaging the glass 'andhaving a bottom edge shaped to intertached to the inner surface of the face mold and extending to the shelf and interlock-' ing therewith.

2. In a show window, the combination of a bar formed with an upstanding flange formed along its edge into a hook and also formed with a shelf, a plate of glass rest ing on the shelf, a face mold engaging the glass and having a bottom edge shaped to interlock under the hook-shaped edge of the said flange, and invisible fasteners permanently secured to the inner surface of the mold and having an interlocking engage ment only with the said shelf.

3. In a show window, the'combination of a bar having two parallel portions connected by a gutter which is provided with apertures inits bottom, one portion forming a shelf which has apertures, a plate of glass resting on the said shelf, a face mold having an interlocking engagement with the said bar and engaging the plate of glass,

and fasteners carried by the mold and eX tending through the apertures of the said shelf, said fasteners being accessible through the openings in the gutter for interlocking the said fasteners with the shelf.

l. In a show window, the combination of a chambered bar having a glass-supporting shelf and a gutter behind the shelf, said gut ter'being provided with openings in its bottom and the bar having a front wall provided with drainage openings, a plate of glass resting on'the shelf, and a face mold engaged with the glass and fastened to the said bar, said chambered bar having a hookshaped flange at its front and the bottom edge of the mold being bent back to interlock with the hook-shaped portion of the flan e.
